A divorced woman, 37, was arrested after leaving two sons, aged seven and 12, unattended at home in Wong Tai Sin. The eldest boy called their father on Thursday night, saying they had been left alone at home in Lok Fu Estate, and the father called police at 9.20pm. The woman went out with her five-year-old son, a police investigator said. She was released on bail and will report back to police this month. The boys were unhurt.
